Model of planning for production of grain in farm family: scenarios socio-economic and financial

During the last ten years, some studies with financial emphasis have proposed technical plan policies for a crop production farm system located on Paracatu-MG. Based on agro-technical aspects of those studies and considering financial aspects like: monthly expenses and long-term investments, the present article represents those production systems by means of a mixed integer dynamic linear mathematical programming model where monthly dynamic treatment and a planning horizon of ten years and five months are stated for production and financial activities. Considering recent government financial policies for farmers, the model is applied to two distinct situations derived from the use of short and long term loans for Brazilian agricultural sector. Scored results and an analysis on social-economic and financial feasibility of the system are also drawn.
